I'm a week into my new Roamio / Mini setup. Everything works great and I'm really happy. However, I just noticed the remotes are different. The mini one is much bigger and the buttons are configured slightly different, with the "back" button missing altogether. Why is this?

Sure they could be the same if they wanted them to. The remote just wouldn't use RF mode with the Mini.

Exactly, if there is any future updates with the Mini remote all they have to do is change it to the newer style that Roamios have. Thank would make better business and support sense. They could even include the RF adapter if they wanted to but that would increase costs.

I am sure the Roamio Remote cost more also, so if your going to put in a more expensive remote with built in RF and find me you also should change the Mini hardware to work with this remote, otherwise why spend the extra money on the Mini.

Well with the RF dongle the "low battery" message would work, along with, you know, the reliability of the RF connection itself. Something could would be if they could add the "find me" function built into the dongle itself via a button that can be pressed with audio playing out the audio connection/HDMI.

It does...there is a button on the dongle that you use to pair it with the remote. Once paired, pressing that button will cause the paired remote to play the "find me" jingle on the Roamio or Slide pro remotes.

Not sure why you would want it to play through HDMI...that would come from the speakers, not the remote.

I've looked through the Tivo website, but I don't see an RF dongle for the mini that allows the Roamio slide pro remote to work with it?

Edit:
After looking though the support documentation for the Slide Pro, it looks like the RF dongle is included when you by the remote separately. Is there any reason to buy the Slide Pro for the Premier/Mini if the dongle is included with the one for the Roamio?

I think you have that backwards. The dongle is included with the Premiere/Mini version as mentioned above, not the Roamio.
